If theta is the acute angle between the lines given by x^(2)-2pxy+y^(2)=0 , then

If theta is the acute angle between the lines given by x^(2)-2pxy+y^(2)=0 , then

If theta is the acute angle between the lines given by ax^(2) + 2hxy + by^(2) = 0 then prove that tan theta = |(2 sqrt (h^(2) - ab))/(a + b)| . Hence find acute angle between the lines 2x^(2) + 7xy + 3y^(2) = 0

If theta is the angle between the lines represented by ax^(2)+2hxy+by^(2)=0 , then tantheta=

If theta is the acute angle between the lines 6x^(2)+11xy+3y^(2)=0 ,then tan theta

If theta is the measure of acute angle between the pair of line repseented by ax^(2) + 2hxy + by^(2) = 0 , then prove that tan theta = |(2sqrt(h^(2) - ab))/(a+b)|,a + b ne 0 Hence find the acture angle between the lines x^(2) - 4xy + y^(2) = 0

If theta is the measure of the acute angle between the lines represented by equation ax^(2)+2hx+by^(2)=0 , then prove that tan theta =|(2sqrt(h^(2)-ab))/(a+b)| where a+b ne 0 and ne 0. Find the condition for coincident lines.

If theta is the angle between the lines represented by ax^(2)+2hxy+by^(2)=0 then show that Cos theta=(|a+b|)/(sqrt((a-b)^(2)+4h^(2)))

If the acute angle between the lines x^(2)-4hxy+3y^(2)=0 is 60^(@) then h=

If the acute angle between the lines x^(2)-4hxy+3y^(2)=0 is 60^(@) then h=
